I have three Adaptall-2 mounts for Minolta. Only two have packages marked Adaptall-2 even though the mounts themselves are all marked Adaptall-2. That's odd, but I can handle it.
The top box is what it should be -- Minolta-MD -- and the mount looks as it should with f-stops from f1.4 to f32.
The second box is marked Minolta-MD-L, and the mount is identical to the one in box #1. I've never seen a Minolta MD labelled MD-L. Anyone have any idea what that might mean? I know Minolta made some tele-converters that were marked "-L" meaning they were designed for lenses that were 300mm or longer, but that makes no sense with a lens mount.
The third box is even weirder. It is marked for lenses with maximum apertures of f2.8 and f5.6 -- not f2.0 or f2.5 or f3.5 or f4 or f4.5 or f8 -- and the mount itself has an additional sticker saying the same thing. The only other difference I can see in the mount is that the f-stops only go to f2. There is no f1.4 setting, as with the other two mounts. I'm not familiar with all of Tamron's Adaptall-2 lenses, but I assume they have other lenses -- than the four listed on the box -- that have maximum apertures of f2.8 or f5.6, nor can I think of a reason why they would do this. And why would a normal Adaptall-2 mount, like #1 and #2 not work on these four f2.8 and f5.6 lenses?
Does anyone have any explanation for this wacky mystery?
